 --To set readonly false for secondary server to forcefully to take this as primary 

as standalone node.

 We can take one of the node forcefully as read write from the latest gtids node.

mysql> DROP DATABASE mysql_innodb_cluster_metadata;

Query OK, 15 rows affected (0.13 sec)

mysql>  SET GLOBAL READ_ONLY=0;

ERROR 2006 (HY000): MySQL server has gone away

Query OK, 0 rows affected (0.00 sec)

mysql> go

Then inform application team to connect this database server ip directly in 

their connection string instead of mysql router way.
